A small scale demonstration of renewable energy, this wind generator can be used with a voltmeter or datalogger to measure and monitor output.

• Size: 15.2×10.2×15.2 cm

It can also be used to illuminate an LED and illustrate the conversion of energy. Its low-inertia electric motor functions as a generator and is driven by a plastic impeller.

A cold air blower can be used to turn the impeller resulting in a low voltage DC output at the two 4 mm sockets.
